[0008]
[Action]
The rectangular plate stacking apparatus according to claim 1 is supplied to the stacking unit. Uneven or flat Before lifting the square plate by the lifting means, the upper and lower surfaces (both front and back surfaces) are reversed by the reversing means. The inverted rectangular plate (for example, the outer wall board) supplied to the stack portion by the artificial means or the mechanical means is held by the lifting means (for example, negative pressure, adhesive force, magnetic force, etc.) and lifted once. Before or after supplying the next square plate to the stack without turning it upside down, the supply means is driven to reverse the sheet that is formed to cover the opposing surface (front side) of the square plate. Is supplied between the opposing surfaces (between the surfaces) of the rectangular plate and the non-inverted rectangular plate. The inverted square plate held by the lifting means is superposed on the non-inverted square plate supplied to the stacking section, and formed between the opposing surfaces of the square plates stacked up and down, for example, with synthetic rubber, soft resin, etc. Since the laid sheet is laid, it is possible to reliably prevent the overlapping surface of the rectangular plate from being scratched or uneven, broken or damaged during transportation or stacking. In addition, the contact resistance of the sheets can positively prevent displacement of the stacked positions of the rectangular plates stacked up and down, and a plurality of rectangular plates can be supplied while being aligned vertically.
[0009]
The square plate stacking apparatus according to claim 2 is combined with the operation according to claim 1 above, when one adsorber or a plurality of adsorbents are pressed against the uneven surface of the square plate, A gap is formed, and the negative pressure due to the adsorbent part or plural adsorbents decreases, but the switching means is driven to cancel the adsorbing by the adsorbent part or plural adsorbents with reduced negative pressure. As a result, the negative pressure due to the other part of the adsorber or the remaining adsorber becomes high, and the negative pressure necessary to adsorb and hold the rectangular plate can be stably obtained.
[0010]
The square plate stacking apparatus according to claim 3 is combined with the operation according to claim 1 or 2, and after the sheet is supplied between the opposing surfaces of the square plates stacked vertically, the moving means is driven to The rectangular plates are moved relative to each other in the direction of superposition, the upper and lower rectangular plates are brought close to or in contact with each other, and the sheet is laid between the opposing surfaces, so the orientation and position of the sheet are displaced during laying.

According to the present invention, a sheet formed in a size that covers the entire opposing surface of the rectangular plate is laid between the opposing surfaces of the rectangular plates that are stacked one above the other. It is possible to surely prevent the surface from being scratched or uneven, broken or damaged. In addition, the contact resistance of the sheets can positively prevent displacement of the stacked positions of the rectangular plates stacked up and down, and a plurality of rectangular plates can be supplied while being aligned vertically.
[0012]
In addition, when one or more adsorbents are pressed against the uneven surface of the square plate, a gap is formed on the adsorbing surface of the adsorber and the negative pressure by the adsorber decreases, but the switching means is driven. By releasing the adsorption by a part of the adsorbent or the plurality of adsorbents whose negative pressure has decreased, the negative pressure by the other part of the adsorber or the remaining adsorbent becomes higher, and the square plate is adsorbed and held. Therefore, the rectangular plate can be stacked stably.
[0013]
Furthermore, since the upper and lower rectangular plates are moved relative to each other in the direction of superposition, the upper and lower rectangular plates are brought close to or in contact with each other, and a sheet is laid between the opposing surfaces. Can be reliably prevented and the sheet can be laid in a state in which the opposing surface of the rectangular plate is covered.

Transfer one outer wall board A to…. When the non-inverted outer wall board A is transported to the reversing part C, the transporting of the receiving belt 12 is stopped based on detection by a photoelectric sensor or the like, and then, as shown in FIGS. The upper and lower surfaces of the outer wall board A are pressed and held. The rotary frame 10 is rotated so that the outer wall board A held by the holding pads 13... Is turned upside down (for example, about 180 degrees) so that the front side faces downward. After inversion, the holding by the holding pads 13 is released, and the inverted outer wall board A is transferred to the lower receiving belts 12.
[0037]
Next, as shown in FIGS. 4 and 10, the inverted outer wall board A placed on the receiving belts 12 is transferred to the second conveyor 3, and the outer wall board A placed on the second conveyor 3. Is transported to the stacking part D while facing down. When the inverted outer wall board A is conveyed to the stacking section D, the outer wall board A is stopped by the stopper 41, and the width adjusting plates 51 and 51 are brought into contact with both ends of the outer wall board A so that the two outer wall boards A and A are aligned so that they are stacked vertically.

Board A is sucked and held. At the same time, the holding plates 49 and 49 are pressed and held at both ends of the outer wall board A sucked and held by the suction unit 28. At this time, when the suction pad 29 is pressed against the uneven surface of the outer wall board A, a gap is formed in the suction surface of the suction pad 29, and the negative pressure in the suction chamber 30 formed in communication with the suction hole 29a is reduced. However, based on the detection by the pressure sensor or the like, the damper 39 of the switching box 34 connected to the intake chamber 30 is closed and the intake air is shut off, so that the negative pressure generated in the other intake chambers 30 and 30 is increased. The negative pressure required for adsorbing and holding the outer wall board A is obtained.
[0039]
Next, as shown in FIG. 12, the outer wall board A held by the suction unit 28 is once lifted to a height that allows the operation of the supply mechanism 6, and then held by holding plates 71 and 72 constituting the supply mechanism 6.

On the other hand, when the next outer wall board A is conveyed to the reversing section C, the reversing mechanism 4 is not driven, and the lower receiving belts 12 are rotated in the feeding direction, so that the first conveyor 2 to the second conveyor 3 are driven. The outer wall board A is conveyed to the stacking part D with the outer wall board A facing up. When the non-inverted outer wall board A is transported to the stacking part D, the transport of the outer wall board A is stopped by the stopper 41, and the outer wall board A is width-adjusted by the width adjusting plates 51, 51.
[0041]
Next, as shown in FIG. 13, the elevator 46 is raised, the non-inverted outer wall board A is lifted in the face-up state, and is brought close to or in contact with the surface side of the outer wall board A held by the suction unit 28. Before superposing the outer wall boards A and A, the protective sheet B drawn on the receiving plate 63 of the separating portion 62 is pressed by the pressing members 64 and 66, and the protective sheet B drawn out between the outer wall boards A and A is obtained. The rear end side is cut with a cutting blade 69 to separate the protective sheet B into a size that covers the surface side of the outer wall board A.
[0042]
Next, the separated protective sheet B is pulled slightly, and the protective sheet B is pulled out to a position where the outer wall boards A and A are covered, and then the suction unit 28 is lowered and placed on the lifting platform 46. The outer wall board A held by the suction unit 28 is superposed on the outer wall board A. After the inverted outer wall board A is placed on the non-reversed outer wall board A placed on the lifting platform 46, the surface side of the outer wall boards A and A are brought into contact with each other, and the protective sheet B is held, and then the suction unit 28 is released, the pressing by the pressing member 66 is released, the holding by the holding plates 71 and 72 is released, and the entire surface of the outer wall boards A and A is covered and protected by the protective sheet B.

The stopper 41 is immersed, and the outer wall boards A and A placed on the second conveyor 3 are conveyed and supplied to the next process while being stacked vertically. Similarly, the mechanisms 4, 5 and 6 are driven to reverse the outer wall board A transported first, and the outer wall board A transported next is not reversed. When the non-inverted outer wall board A is stacked up and down, a protective sheet B is laid between the opposing surfaces to cover and protect the surface side of the outer wall board A.
[0044]
As described above, since the protective sheet B formed so as to cover the entire surface of the outer wall board A is laid between the surfaces of the outer wall boards A and A stacked vertically, the outer wall is used during transportation or stacking. It is possible to prevent the surface of the board A from being scratched or uneven, or to be damaged or damaged, and to reliably prevent dimensional accuracy and commercial value from being impaired. In addition, the contact resistance of the protective sheet B can actively prevent the stacking position of the outer wall boards A, A stacked one above the other, and the two outer wall boards A, A can be kept in a state where they are aligned vertically. It can be conveyed and supplied to the next process.
